The Republican Party is big on leadership these days, and especially fond of demanding that the United States "lead from the front."This was a central theme in of John McCain’s recent sally right here at Foreign Policy, as well as Condoleezza Rice’s speech at the GOP convention in Tampa. Among other things, it reminds us that the Republican Party’s foreign policy gurus aren’t very good strategists. (The Bush administration’s disastrous handling of foreign policy showed this all too clearly, but it’s nice to have a reminder).

In fact, the idea that the United States should always try to "lead" is completely bone-headed."Exerting leadership" is not the central objective of foreign policy; it is a means to an end but not an end in itself. The central purpose of foreign policy is to maximize the nation’s security and well-being. If exerting "leadership" contributes to these ends, fine, but there will be many occasions when the smart strategy is to hold back and pass the buck to someone else. Blindly declaring that the United States must always go to enormous lengths to lead, and must constantly strive to reassure allies who need us far more than we need them, is mere jingoistic hubris. It’s an applause line, but not a strategy.

The United States would be well-served by a more selective approach to "global leadership." It is not a foreign policy achievement when the United States gets stuck dealing with an intractable quagmire like Afghanistan — at a cost of a half a trillion dollars and 2,000 lives — or when it finds itself waging drone wars in half a dozen countries. A real achievement would have been to find a way to shift the burden of this problem onto others, and especially onto the backs of potential U.S. adversaries. We congratulate ourselves on finally tracking down Osama bin Laden, but the real winners over the past decade have been countries like China, which have concentrated on building up power at home while the United States bled itself white in a series of pointless foreign adventures.

Furthermore, America’s reflexive urge to be in charge has other negative consequences. It has allowed our most important allies to free-ride for decades, to the point that they are increasingly liabilities rather than assets. NATO’s European members spend a mere 1.7 percent on average on defense these days (and that number is going down), and none of these countries can mount a serious military operation anywhere without a lot of American help. Why? Because Uncle Sucker has spent the last 50 years doing it for them. Much the same story is true in Asia, where countries like Japan want lots of American protection but don’t want to spend any money defending themselves. Washington ends up with not with allies but with dependents, and we see it as a victory whenever some new country requires our protection.

This demand that the United States constantly "lead from the front" also makes it easier for other states to drag us into their quarrels. Georgia tried to sucker us into its dispute with Russia a few years ago (and if McCain had been in charge, it would have succeeded), and Israel is still trying to get America to bomb Iran on its behalf. Countries like Vietnam and the Philippines are trying to push the United States to confront China over issues like the South China Sea, and everybody seems to think the United States should "do something" about Syria. Perhaps we should, but first you need to explain why doing any of these things will make Americans safer or more prosperous here at home, and then you need to convince me that the countries who have a lot more at stake aren’t up to the task. And if some other country wants me to spend American money and risk American lives, they’d better have a lot of skin in the game, too. Finally, if weaker countries want to demand my protection, they’d better be willing to follow my advice on other issues. Otherwise, they’re on their own.

Don’t get me wrong: in some cases the United States should be actively involved and it should exercise a leadership role. It is still the world’s most powerful country, and a return to isolationism would have destabilizing consequences in some areas. But our overall approach to grand strategy should begin by recognizing that the United States is remarkably secure, with no great powers nearby, and most of our current adversaries are much, much weaker. This favorable geopolitical position is an enormous asset; it means that other states tend to worry more about each other than they do about us, and it means many countries will remain eager for U.S. support. Which in turn allows Washington to "play hard to get," and extract lots of concessions from others in exchange for our help. Those who pompously insist that America must always take the lead are throwing this diplomatic asset out the window, and guaranteeing that other states will take advantage of us instead of the other way around. And it should enable us to spend a lot less on national security, thereby easing our budget problems and allowing investments that will ensure our long-term productivity.

It is worth remembering that the United States rose to great-power status by staying out of trouble abroad and by concentrating on building a powerful economy here at home (which is what China is doing today). It also helped that the other great powers bankrupted themselves through several ruinous wars. The United States fought in two of those wars, but we got in late, suffered far fewer losses, and were in a better position to "win the peace" afterwards. The world has changed somewhat since then, and America’s global role is and should be more substantial, but there is still a valuable lesson there. But don’t expect Romney & Co. to absorb it.
